Persian Pantheon Invasion is a time-limited Event that takes place once a month. While it is on, participating Coalitions must defend their Pantheons against five Attack Waves from Persians in exchange for spectacular Rewards.
A Coalition can participate if its Coalition Hegemon or a Polemarch authorizes it to do so, and only if it controls at least one Pantheon.
Rules
While the Event is on, Xerxes will launch five Attack Waves upon the Pantheons of participating Coalitions. Each Wave will be launched randomly during a four-hour Attack Window, with the first Attack Window opening the moment the Event begins. Attack Windows are separated by four-hour cooldown periods. During cooldown periods, Persian forces will not attack the Pantheons.
If a Coalition controls multiple Pantheons, Persian forces will attack them one by one in random order. Each battle at a Pantheon will generate a Battle Report.
To repel an Attack Wave, a Coalition must win at least 75% of the battles that take place during that Wave. If a Coalition fails to repel two Attack Waves in a row or no longer controls at least one Pantheon, it will no longer be able to participate in the Event. You can see both how many Pantheons your Coalition has successfully defended and how many were attacked by Persian forces in the “Pantheons Defended” column of the Event window.
If a Coalition loses a battle at a Pantheon to Persian forces during the Event, this cannot result in the Pantheon being captured or its Level downgraded.
Note that while the Event is on, Pantheons held by participating Coalitions will only be attacked in line with the rules of the Event and will not be subject to any other attacks from Persian forces.
Rewards
After each battle, Coalitions will earn Orichalcum. The amount of Orichalcum earned will be shown in Battle Reports. Also, repelling Attack Waves will earn Coalition Members Coalition Gold, which can be spent at the Coalition Shop.
